Area background develops on the drum. In a specific area. The background moves right and left across the page. It shows up after about 20 minutes of running. It will go away after about 20 minutes of resting but returns. I already replaced the drum,developer housing, pm has been done, all zero graphic components have been cleaned including laser slit glass. Any suggestion would be great. Thank you!

May be the drum temperature sensor (most likely) or printer driver board.

You could try replacing the coronas, then you would cover most areas that could cause your problem.
